Abstract: A computer implemented method for analyzing operation of cells of a communications network is provided.

Abstract: A computer implemented method for evaluating effect of a change made in a communication network. The method is performed by comparing values of the performance indicator in a cell of interest before and after the change to obtain a first comparison result; comparing values of the performance indicator in a set of reference cells before and after the change to obtain a second comparison result; and evaluating the effect of the change made in the communication network based on difference between the first comparison result and the second comparison result.

Abstract: A computer implemented method of cell overlap analysis of a communication network. The method includes determining coverage area of a first and a second cell of the communication network, wherein determination of the coverage area of a cell is based on user distribution in the respective cell; determining intersecting area as an area where the determined coverage area of the first cell and the determined coverage area of the second cell overlap; and determining a first impact value reflecting impact of the overlap on the first cell as a ratio of the determined intersecting area and the determined coverage area of the first cell.
